The Shard opened its viewing platforms to the public today, prompting the
question: how much is too much to pay for the best views of London?

If you book online in advance, it costs £24.95 a person to step on to the 72nd
floor, feel the wind in your hair and the mist on your face, and marvel at
the city’s most famous landmarks made miniature.

If you turn up on the day, without a reservation, the price rises to £29.95
for the next available slot.
